calculations at the B3LYP/6-31G(d,p) level of theory. This property has been explored in the case of pyridyl-substituted systems which exhibit in particular a high binding affinity and selectivity for Pb2+ (log K = 3.5 in CH2Cl2/CH3CN), as shown by UV/Vis and 1H NMR titrations as well as by remarkable colorimetric and electrochemical signaling.(© Wiley-VCH Verlag GmbH & Co.

已经设计并合成了一系列包含四硫富瓦烯部分作为供体单元的供体-π-受体系统。B3LYP/6-31G(d,p) 理论水平的计算证明并支持了亚胺 (–C=N–) 键作为共轭 π-linker 在促进分子内电荷转移方面的效率。已经在吡啶基取代系统的情况下探索了这种特性,该系统特别表现出对 Pb2+ 的高结合亲和力和选择性(在 CH2Cl2/CH3CN 中 log K = 3.5),如 UV/Vis 和 1H NMR 滴定以及通过显着的比色和电化学信号。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)
